Abstract
This article introduces a novel low-cost scheme for implementing in-building/campus wide remote antenna units for next generation radio-over-fiber systems using the photonic active integrated antenna concept, whereby photonic devices can be integrated directly with planar antennas. De-embedded input impedance of a state-of-the-art 40-GHz mode-locked laser is measured, and the device is matched directly to the nonradiating edge of a rectangular-microstrip-patch antenna. Wireless hybrid mode locking is then demonstrated for a maximum wireless range of 15 cm. (C) 2012 Wiley Periodicals, Inc.
